You said: Improving one's voice for the sake of the listener is considered shirk (associating partners with Allah), so how is the hadith answered: "If I had known you, I would have adorned you with adornment"?

Question:
He says: Honorable Shaykh, may Allah grant you success. It was narrated from Abu Musa al-Ash'ari (may Allah be pleased with him) that he said to the Prophet (peace and blessings be upon him): "If I had known you, I would have adorned you with adornment." How is this reconciled with the statement that improving one's voice for the sake of the listener is considered shirk?

Answer:
If the intention behind it is praise and eulogy, if the intention behind it is praise and eulogy, then this is considered riya' (showing off in worship). But if the intention behind it is to benefit the listener, if the intention behind it is to benefit the listener, and Abu Musa intended that the Messenger was pleased with this recitation and this voice. Yes, Allah's blessing upon Abu Musa. So if the intention is good, there is no harm. But if the intention is praise and eulogy, that is the problematic part. Yes.
